Bonjour,

J'ai un probleme de configuration sur un PIX 501.

Le pix est derrière un routeur internet Zyxel. Le routeur est configuré pour forwarder tout ce qui vient de l´exterieur vers l´ip externe du PIX.

Les adresses sont les suivantes :
IP interne du Zyxel 192.168.0.2
IP externe du PIX 192.168.0.1
IP interne du PIX 192.168.1.1
IP du serveur exchange 192.168.1.2
IP du serveur "formation" 192.168.1.100
IP d´un hôte (wks-15) a acceder depuis l´exterieur 192.168.1.16

Je NAT les adresses de la façon suivante (enfin je pense) :
192.168.1.2 <> 192.168.0.3
192.168.1.100 <> 192.168.0.4
192.168.1.16 <> 192.168.0.5

Les ports ouverts sur le serveur exchange fonctionnent correctement (smtp, http, https et rdp).

Je veux faire du PAT et diriger ce qui arrive sur les ports 48620 et 48621 vers 192.168.1.100 et le port 48622 vers 192.168.1.16. Toutes mes tentatives de connexion sur ces ports sont dirigés vers 192.168.0.3 (le serveur exchange)je le vois dans les logs et sont donc rejetées.

Je vous précises que j´ai configuré le firewall avec l´utilitaire JAVA intégré au PIX car je ne connais pas très bien les commandes :

Pouvez-vous me dire ce qui ne va pas dans ma config ?
